1. Buying a brand new Kenwood replacement filament transformer. probably highly unlikely to find one "just like that"2. Buying a used good one from someone parting out a 922 amp. More likely than above, but you'll have to wait until someone parts one3. Retrofitting a completely different unit 10v@15 amps that you can get to fit in the space allotted. Possible maybe4. Buying another amp as parts that is in poor shape or not working for more money than just the transformer is worth. Highly probable 5. Buying another nice TL-922 maybe without tubes in perfect working order and moving your tubes into it and parting out your unit or selling as is. This can probably be done today for the right price.

Other than those options I don't know what else there is. Pick one that suits your time frame and pursue it.

The 922 is to nice of an amp to "part out" or other drastic thoughts. Either rewind the transformer yourself (Low voltage, high current transformers are fairly easily rewindable - HV transformers is another animal!) I have wound and rewound several LV transformers and everyone worked and are still working after 30+ years!

If you are not comfortable with this solution, follow 1H's suggestion and get a pro to rewind it. It shouldn't cost THAT much, especially when it will bring your nice 922 back to life!

If the primary is on the outside you only need to rewind that part as the secondary almost NEVER FAILS. Now its easy to see if the primary is outside or inside. The finer primary wire is the weak point as the iron never goes bad. Let us know how you do with this, Woody

When you have the amp fixed you might want to consider adding a slow blow 1 amp fuse to the primary of the filament transformer. I also added the same fuse to the secondary 80V winding. This will protect the transformer from damage when you have a bad tube with a shorted grid to cathode.
